Using a 50K MCP4341 digital pot and I would like the output to be logarithmic. The input value written to the pot is 0 - 127.
I have tried this, log10(value) * 60, which gives a fast rise at the start and then a slower rise at the end. That is what I want, but I wonder if there is a better way than *60.
Also I would like the option to have a slow rise at the start and a faster rise at the end. How is that done.
